New USPTO Rules of Professional Conduct in Effect
Non-registered practitioners may, in limited circumstances, be permitted to appear before the Patent Trial & Appeal Board (PTAB) on a pro hac vice basis. 37 C.F.R § 42.10(c). Previously, in IPR (IPR2013-00010) (order here), the requirements for the motion and accompanying declaration were outlined.
As the Rules of Professional Conduct have been updated since the issuance of the above order, a new Model Order has been issued (here) to update factor (vi) so that it now properly references Part 11, rather than Part 10 of Title 37, Code of Federal Regulations (which was deleted in May of this year).
